MACHINE FOR SAWING THE MOUTHS OF MOLDING-PLANES.

SPECIFICATION forming part of Letters Patent No. 431,382, dated July 1, 1890.

- Application filed February 15, 1890- $erial No. 340,542. (No model.)

To all whom it may concern: Figure 1 is a side elevation. Fig. 2 is a Be it known that I, JOSEPH A. MONTGOM- front elevation. Figs. 3 and at are views in ERY, of Sandusky, in the county of Erie and perspective of angle-plate or guide-block and State of Ohio, have invented certain new and gage detached. Fig. 5 is a plan of the tilting- 5 useful Improvements in Machines for Sawing table detached. Fig. 6 is an end elevation of the Mouths of Molding -Planes; and I do a stop, hereinafter described. Figs. '7, S, and hereby declare the following to be a full, clear, 9 are views in perspective of planes illustratand exact description of the invention, such ing the work done on this machine. as will enable others skilled in the art to which A represents a supporting frame or stand- [0 it pertains to make and use the same. ard, if preferred, on top of which is secured a My invention relates to improvements in horizontal frame A, the latter having boxes machines for sawing the mouths of moldinga, in which is journaled the saw-mandrel 1-3,. planes, &c.; and it consists in certain features the arrangement being such that the saw 6 of construction and in combination of parts overhangs the supporting-frame some little I 5 hereinafter described, and pointed out in the distance. The saw-mandrel is provided with 6 5 claims. driving and loose pulleys, as shown at B.

There are a great variety of molding-planes These frames may be varied indefinitely, acand rab'oet-planes, &c., in whichthe respectcording to the judgment of the, builder, and ive plane-irons are set at various inclinations they may be made of wood or metal, as pre- 20 and at various angles transversely, some of ferred. The framesAA (shown inthe drawthe plane-irons extending across the face of ings) are supposed to be of metal and may the plane and others extending only part way be cast integral, if preferred. Frame A is proacross, and some planes have two plane-irons, vided with vertical ways a, on which the prione 011 each side thereof. The so-called mary table 0 reciprocates vertically. Frame 2 5 mouthorslot,whereintheplane-ironisset, A has a laterallyprojecting boss a that is usually cutby means of a small circular saw serves as a stepping for the upright screw D. on an ordinarysaw-table, and heretofore apat- This screw engages nut O of the primary tern was made for each variety of plane, a pat table O, the screw being provided with handtern comprising ablock of wood,thetopsurface wheel d for operating the same, whereby ta- 0 thereof being adapted to receive and fit the ble 0 is raised or lowered. Table 0 is pro- 8o plane and the bottom surface being adapted vided with horizontal longitudinal ways 0 c, to rest and slide on the saw-table, the block on which is mounted slide E, the latter'being or pattern being of such angular or wedgereciprocated on these ways by hand in the shaped form lengthwise and crosswise, and direction toward and from the saw. Slide E 5 having a beveled end for engaging the guide is provided with upwardly-projecting arms of the saw-table, that the plane was made to E E to which arms are pivotally attached engage the saw at the desired angle. These the depending arms ff of tilting table F, patterns had to be made with great care and the axial rod e having an easy fit in the holes accuracy, and each workman was supposed of these two sets of arms, so that the table F 40 to provide hisown patterns, so that a planemay tilt laterally. Rod e is provided with a factory was likely to be cumbered with absoshoulder at e for engaging collar 6 the latter lutely cart-loads of these patterns. The patbeing mounted loosely on the rod, and the reterns of different workmen would likely vary duced section of the rod that extends through more or less, so that the work in the aggrethe holes of arms E and fis provided outside 45 gate was not uniform and the patterns were arm E with nuts 6 WVith such construction 5 likely to warp and wear, and in one way and the parts are easily assembled, and by tightanother much difficulty was encountered. I ening nut e arms E and f are clamped tohave therefore devised a machine for doing gether, whereby the tilting table maybe held such work, the same being illustrated in the rigidly in its adjusted position, arms E and 50 accompanying drawings. f meantime being slightly separated. Table F has a slot F at the end thereof that is next angle-plate being pivotally secured to the ta ble by means of bolt or stud G, so that it may be swung around to different positions. The upright face of the angle-plate that serves as a rest or a guide for the work is provided with a longitudinal recess g, the same having undercut walls, and in this recess is fitted the body of gage H. This gage is bent at right angles, so that member h thereof is in position for engaging the endof the plane, the gage being held in adjustment by means of set-screw g.

I, J, and L represent three varieties of planes that may serve to illustrate the Work done on this machine, these planes having, respectively, throats i, j, and Z. These planes are laid flatwise on the tilting table F, with the face of the plane of course presenting toward the'saw and the one end of the plane bearing against member h of the gage, and the back of the plane bearing against the face of plate G. If the throat is to be cut through and through the plane, as shown in Figs. 7 and 8, the tables, by means of screw D, are adjusted vertically to bring the work about opposite the 'center of the saw. If, as in 7 case of plane 1, Fig. 8, the throat j is to be cut square across the face of the plane, table F is adjusted to and secured in a horizontal position and plate G is adjusted and secured at the proper angle relative to table F. Next, gage H is adjusted to gage the mouth lengthwise the plane, after which the plane is forced by hand against the saw, and any number of planes of this varietymay be operated upon in quicksuccession and themouths cut therein with perfect uniformity.

In case of plane I, Fig. 7, as the mouth 2' thereof extends obliquely across the face of the plane, in addition to the adjustment of parts already mentioned table F is tilted to the one side, so that the face thereof corresponds with the angle of the mouth of the plane crosswise the face of the plane. In case I of plane L, Fig. 9, having two throats Z Z, each of which only extends part way through the plane, in addition to the adjustment aforesaid the table is lowered so that a portion of the plane can pass under the saw, the saw cutting a mouth of the required depth, and when mouths Z of the batch of planes have been cut the machine is readjusted for cutting mouths Z, and of course the plane is reversed.

A stop'of some kind is provided to limit the movement of v slideEtoward the saw-for instance, stop K.

In plane factories the different Varieties of planes are made up in large batches, usually enough to supply the trade for, say, a year. The one plane of a batch is laid out by means of a bevel square or pattern to indicate the location, inclination, and angle of the mouth, and from this plane the machine is set in a few moments time.

I have reduced thema'chine to practice and its operations are entirely satisfactory, and by means thereof is elfected a very great saving over the old methods of doing this kind of work.

What I claim is- 1. The combination, with a supportingframe and saw, of a primary table mounted on such frame, a screw connecting with the frame and with the table for actuating the latter vertically, a slide mounted on the table and.

having an end movement toward and from the saw, a laterally-tilting table mounted on the slide, and a rest mounted on and pivotally connected with the tilting table, substantially as set forth.

2. The combination, with a supportingframe and a saw overhanging the frame, of a Vertically-adjustable table mounted on such frame, the slide mounted on the table, a laterally-tilting table mounted on the slide, a rest mounted on and pivotally connected with the tilting table, and a gage operatively connected with such rest, substantially as set forth.

In testimony whereof I sign this specification, in the presence of two witnesses,this 30th day of January, 1890.
